Cannot find codec for audio format 0x726D6173.
Read DOCS/HTML/en/codecs.html!
Audio: no sound
Video: no video
Any suggestions for alternate approaches, pointers on how & what to
install in terms of a codec, or maybe a way to convert these files
(ideally without transcoding degradation)?
These audio files were created by the android app "Voice Recorder".
Note that Debian hobbles some apps (like mplayer and ffmpeg) because of freedom issues. That's why www.debian-multimedia.org exists.
Did you Google "linux play 3gp"? If the d-mm.org packages don't work, then Google might.
